White Shark

Very few animals generate the mixture of fascination and terror as the great white shark. Unfortunately, the terror-associated, anti-shark sentiment has led to the unnecessary slaughter of many animals. White sharks have been listed for international protection under the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) Appendix II and were listed as vulnerable by the International Union for the Conservation of Nature. A...

Offield Center Billfish Studies

The Offield Center for Billfish Studies has been conducting groundbreaking research on marlin species since 2000 and has grown into the largest billfish program in the world with over 450 satellite popup tags deployed on marlin around the globe. Paxson Offield was instrumental in developing MCSI’s largest research program, the The Offield Center for Billfish Studies (OCBS). OCBS has been conducting groundbreaking research on marlin species since 2000 and has grown...

Channel Islands Tracking

From 2000 to 2006 Dr. Michael Domeier and scientists with the Pfleger Institute of Environmental Research performed an involved study of the movements of the giant sea bass, Stereolepis gigas, and white seabass, Atractoscion nobilis, in the California Channel Islands. This study utilized one of the largest acoustic receiver arrays in the world, encompassing five of the Channel Islands and three points along the mainland (Point Vicente, Point Dume, and Point...

MCSI Guadalupe Island Expedition 2019

MCSI is offering another Guadalupe Island research expedition in 2019! Experience great white shark cage diving with the pioneer of Guadalupe Island white shark research! Michael Domeier and Nicole Nasby-Lucas have been studying the white sharks of Guadalupe Island since 1999 using satellite tagging and photo-identification! This amazing cage diving experience is October 30 – November 4, 2019 aboard the Nautilus Explorer. This ship is 132 feet long, has bathrooms with showers in all staterooms, internet via wifi, and a hot tub on the upper deck! The cost of this trip is tax deductible, and is per person based on double occupancy starting at $4,800.

Bring your cameras since this will be an active research trip where every shark will be examined to determine if it is already in our photo-ID database. New sharks will be named and known sharks will be logged, allowing us to make a new population estimate for Guadalupe Island white sharks. Space is limited so book today! For more information contact nicole@marinecsi.org

Expedition White Shark app

MCSI has now updated the Expedition White Shark app and it is available for both Android and Apple! This app shows tracks for all of our tagged sharks and provides real time tracking data for white sharks tagged at both Guadalupe Island and central California, as well as large shortfin mako sharks tagged in southern California.

Joshua’s amazing journey

Joshua, a 15 foot male Guadalupe Island white shark was SPOT tagged in December of 2016. Since then he has made a surprising trek offshore and then up along the coast of northern California and then traveling back down south! You can follow his amazing journey with the app Expedition White Shark! The app is currently available for Apple products.

Gill Rakers’ amazing journey

Guadalupe Island female white shark Gill Rakers was SPOT tagged in December of 2012. Since then she has made an amazing journey up along the coasts of California and Oregon, back offshore and then into the Sea of Cortez during the known pupping season where it is presumed she went to give birth!

New publication reveals the 2-year migration for adult female white sharks in the northeastern Pacific

MCSI develops new methods for tagging adult white sharks

Scientists at MCSI have been working to improve methods for SPOT tagging adult great white sharks. New methods developed, tested and implemented by MCSI involve a device to prevent gut hooking, soft fishing gear to prevent skin abrasions and constant forward movement to fully irrigate the gills. Sharks tagged in this manner, including the largest white shark to ever be SPOT tagged, were far more vigorous upon release than our previous method that lifted the sharks from the water. We strive to constantly improve our methods to do what is best for the sharks and the scientific community.
